Seasonal synchrony between Saissetia oleae and coccinellid species in Portugues...
Santos, SAP; Pereira, JA; Raimundo, A; Torres, LM; Nogueira, AJAThe black scale, Saissetia oleae (Olivier) (Hemiptera Coceidae), is one of the main olive pests and coecinellids are among the principal predators that feed on scales. The relationships between the temporal abundance or live common coccinellid species [Chilocorus bipustulatus L. Scymnus subvillosus (Goeze), Scymnus mediterraneus lablokoff-Khnzorian, Scymnus interruptus (Goeze), Rhyzabius chrysomeloides (Herbst)...
Response of coccinellid community to the dimethoate application in olive groves...
Santos, SAP; Pereira, JA; Raimundo, A; Torres, LM; Nogueira, AJAIn this work we assessed the effects of the application of dimethoate on the coccinellid community. The field work was carried out on a weekly basis, in two different olive groves, from April to November of 2002 and 2003 and captured coccinellids were identified to species level. Principal response curves (PRC) method was used to analyse the effect of the dimethoate application on the abundance of coccinellid s...
Identification of predator-prey relationships between coccinellids and Saisseti...
Santos, SAP; Pereira, JA; Rodrigues, MD; Torres, LM; Pereira, AMN; Nogueira, AJAA polyclonal antiserum (AS) was developed and characterized for the detection of immature stages of the black-scale, Saissetia oleae, in whole body homogenized field-collected coccinellid species, using an indirect enzyme-linked immunosorbent assay (ELISA). The indirect ELISA showed to be sensitive to the S. oleae AS, detecting a protein content between 0.118 and 0.0374 mu g mL(-1). The specificity of the ELISA...
Voracity of coccinellid species on different phenological stages of the olive p...
Santos, SAP; Pereira, JA; Torres, LM; Nogueira, AJNCoccinellidae are well known predators in agroecosystems. In olive groves they may exert control against scales, such as the black scale, Saissetia oleae (Olivier, 1791). Laboratory studies on the consumption of three phenological stages (eggs, first and second instar nymphs) of S. oleae by four coccinellid species (Chilocorus bipustulatus, Scymnus (Pullus) subvillosus, Scymnus (Mimopullus) mediterraneus and Sc...
